Materials Data on SrSiN2 by Materials Project
SrSiN2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 4-coordinate geometry to five N3- atoms. There are a spread of Sr–N bond distances ranging from 2.61–3.10 Å. Si4+ is bonded to four N3- atoms to form a mixture of corner and edge-sharing SiN4 tetrahedra. There are a spread of Si–N bond distances ranging from 1.72–1.79 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a 3-coordinate geometry to one Sr2+ and two equivalent Si4+ atoms. In the second N3- site, N3- is bonded in a 2-coordinate geometry to four equivalent Sr2+ and two equivalent Si4+ atoms.
